The AlpArray SWATH-D experiment installations in NE Italy

The SWATH-D experiment focuses in the provision of seismic data from a dense seismic network in the Central and Eastern Alps. This dense deployment of 154 stations will complement the larger-scale AlpArray “backbone” network (AlpArray, 2016). SWATH-D will provide high-resolution images from the surface into the upper mantle. SWATH-D focuses on a key area of the Alps where e.g. the hypothesized flip in polarity is suggested to occur, and where the TRANSALP experiment has imaged a jump in the Moho (TRANSALP Working Group, 2002). The data created in this project will be used directly by 20 individual proposals of the MB-4D Priority Program (Mountain Building Processes in Four Dimensions, 2017) of the German Research Foundation (DFG, Deutsche Forschungsgemeinschaft, 1952), and data products derived from it will contribute to an additional 13 proposals. SWATH-D is thus an important link within the MB-4D Priority Program and the international AlpArray communities and a scientific service to many of the proposals within the DFG Priority Program community. Given the extension of the SWATH-D experiment in NE Italy, a specific Memorandum of Understanding between the GFZ and the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS , http://www.inogs.it/) has been signed for the execution of the experiment itself.
